I have had the same problem and is makes it difficult to use my phone. I go to bed with my phone fully charged and when I wake up 8 hours later 60% of the battery capacity is already used up. Before the 47.1.A.12.205 update my phone used maybe 15% of its capacity while I was sleeping. During the day, when I dont use the phone much, it used to maybe use 2% an hour, but not its 6-7%. I got this phone because I hve heard good things about the battery, and the Stamina Mode. But I am not consdering if I should switch brands, because I have to bring an extra battery with me at all times to make sure my phone doesnt die. Is there a fix to this problem? It started once the new update was installed to my phone, in early June.
